Referring more particularly to the ;d 'rawi;ngs, wherein similar.-.refere.nce characters, designate like parts throughout theseveral views the nuline 54 of Fig iew of the 016th hem meral Iv designates generally a main fra lne, of

metal or other suitable material, comprisinga series of pairs of spaced vertical standards or uprights 2 havin longitudinally extending side o rame m m er n r ss f ame em e 4 suitably s a s m.,.t1ie. i th nds" .fi e eqf- A pair of spaced horizontally dis'posed cloth roll 5 vare suitably secured ts ne .7 no .lv i M19 machine, at 'a' point between the lowerend thereof supporting ar n and the top frame members 3, which arms are additionally supported by a pair of spaced struts 8. The projecting ends of a shaft 1, carrying a cloth supply roll 8, are journalled in slotted bearings 8 mounted on the arms 5 to permit of a web of cloth being delivered through the machine, as hereinafter described.

The upper ends of the end uprights 2 project upwardly above the top frame members and are suitably connected together by a spacer bar or the like M. An idler roll journalled in bearing brackets l2, connected adjacent the upper ends of the end uprights 2, permits of the web of cloth 8 passing thereover during the travel thereof and has a tendency to smooth the same. A pair of transversely rollers |3 are journalled in vertical bearing brackets |4, mounted on the side top frame members 3 adjacent the forward end of the machine. The rollers l3 are disposed one above engage with each other, and one end of the lower roller shaft l5 carries a pulley I6 driven by a belt H which travels over a second driven pulley l3, carried by a transverse stub shaft l8 journalled in a bearing 2| formed on the lower end of a substantially L-shaped arm 20. The arm 28 is pivotally connected, as at 22, to a substantially L-shaped bracket 23 suitably connected to the upright 2.

Adjustment of the late the tension of the belt H by means of a vertical rod 24 (Figures 1 and 5) which extends downwardly through an opening 25 in one of the side frame members 3. The lower end of the rod 24 extends through a threaded bore .29 in a block 28, supported between two spaced horizontally disposed arms 21 of the L-shaped bracket 23. Bushings 28' and 28" arranged on either side of the block 28 permit of the rod being rotated therein, for a purpose to be hereinafter described. A threaded portion 26 on the lower end of the rod 24 extends through a block 2| carried by one leg of the L-shaped arm 28. Stop nuts 30 on the lower extremity of the rod 24 and collars 38' and 38", sleeved on the rod above and below the block 2|, enable the rod to move the L-shaped arm 20 about its pivot 22. Thus, an upstanding crank 32, formed on a disc 3| mounted on the upper end of the vertical rod 24, may be manually rotated in the appropriate directions, which causes the arm 20 and pulley I! to be raised or lowered. This adjustment results in the belt |1 being either slackened or tightened which, in turn controls the speed with which the pulley l6 rotates. The pulley I3 is driven by a second pulley 33 on stub shaft I8 in turn driven by a. belt 34 which travels over a pulley 38 carried by a main longitudinal driven shaft 35 journalled in bearings 31 mounted on the frame uprights 2. The shaft 35 is driven by gearing, not shown. in a gear box 38 mounted on the frame, which gearing drives a pulley 38 in turn drivingly connected by a belt 40 with a pulley 4| on a. shaft 43 of an electric motor 42, of conventional construction. When the pulley I6 is driven, as just described, the lower feeding roller I3 is rotated in a clockwise direction, viewing Fig ure 1, which causes the upper roller |3 to be rotated in an opposing or counterclockwise direction so that the rollers engage with and pull the web of cloth therebetween. If will, of course, be understood that the aforementioned adjustment of the L-shaped arm 28 and pulley l3 also moves the pulley 33 to regulate the tension of the belt 34. In other words, both belts l1 and the other and I pulley I9 is effected to reguextending driven feeding 4 34 are simultaneously slackened or tightened, through the adjustment of the arm 20, to control the speed of pulley It. To assist in this feeding of the cloth, the upper roller |3 may have a strip or strips, not shown, suitably applied thereto for frictionaliy engaging the cloth, or the rollers may be knurled or fluted.

As the cloth is fed by the feeding rollers i3 and I4, the'right hand marginal edge of the strip, viewing Figure 1, is caused to pass over a smoothing plate 45 carried by a forwardly extending arm 46 mounted on a vertical rod or post 44. The latter is sleeved through an enlarged cylindrical collar 44 the lower end of which spans or overlaps a gap or slot 41 formed between the horizontal portions or flanges of one top side angle frame member 3 and a second angle frame member 48 which is attached to the cross top frame members 4 by welding or the like, the members 3 and 48 being separated or spaced apart, as best shown in Figure 8 for this purpose of providing the slot or gap 41. The threaded lower end of the rod or post 44 extends through the slot 41 and receives a nut. neither the threads nor nut being shown, so that the post 44 may be clamped in stationary position relative to the frame members 3 and 48 but may upon loosening of the nut, be moved lengthwise in the slot 41 for adjustment purposes. The upper end of the rod or post 44 is formed with a lateral integral extension or arm 50 On which a flat plate 43 is sleeved and supported to project forwardly and downwardly so that the forward end thereof rests on the smoothing plate 45. A pair of screws 53' mounted in the end of the plate 48 are adapted to rest at their lower ends on the plate 45 (see Fig. 2). Thus, when the cloth web is run through the machine one side marginal edge thereof will pass over the smoothing plate 45. Plate 43 is hinged on L-shaped arm 44 so that it can swing freely above the plate 45. Screws 50' are for mounting a yardage counter, not shown, the wheels of which run on the web to give an accurate account of the amount of goods run through the machine. Plate 43 is hinged so that the yardage counter will pass with its own weight against the web.

After passing through the feeding rollers l3 and having its right hand marginal edge smoothed, as just described, the cloth is directed under and thence upwardly over an angularly disposed horizontal bar 5|, as best shown in Figures 1, 2, 3 and 8. One end of the bar extends through a collar 53 on the upper end of a vertical post 52 projecting through a bushing 54 carried by a laterally extending arm 55 on a vertical bracket 56. A flange 51 secured to the bracket 55 is secured to the side top frame member 3 by a bolt or the like 58 so that the bracket is rigidly supported on the frame. The horizontal bar 5| normally extends forwardly and laterally across the frame at an angle of approximately forty-five (45) degrees relative to the longitudinal axis thereof, and the free or unsupported forward end thereof normally terminates at a point ahead of a sewing mechanism to be presently described. The angle of the bar 5| may be adjusted by manu ally swinging the bar bodily about the axis of the vertical post 52 and bushing 54, after a clamping screw 59, mounted on the bushing 54, is rotated to loosen its clamping action on the post 52. When so loosened, the post 52 may be rotated in its bushing, in an obvious manner, so that the bar 5| can be manually swung in the desired direction. The vertical post 52 may also be elevated or lowered in the bu h 54. Thus, the bar him be set at an angle either greater or less than forty-five (45) degrees so that the dimeter of the cloth tube forin'ed thereb'ymay be made smaller or larger. If it is arranged at an angle less than forty-five (45) degrees the tube will be smaller, and if it is set at "an angle over forty-five (45) degrees the tube will be larger. It

will also .be noted that the bar 5| may be readily removed from the Collar 53 on the post 52 by sliding the same therethrough after loosening a clamping screw '60 in the collar 53. By virtue of the approximate 45 angle of the bar 5|, relative to the machine frame, the continuously movstrip of cloth in passing under and over the bar thence directed transversely of the frame, at an angle, after which the cloth is acted upon by cloth supporting and rornnng devices, p'resently to be described, which cause the left 'selv'age of the cloth to overlie the right hand marginal edge or in proper position for the edges of the clothb'eing' stitched 'or otherwise secured'to'geth'e'r on the bias, as also hereinafter described.

During the travel of the continuously moving strip of cloth under and over the angle bar 51, the right hand marginal edge of the cloth is passed between a .pair of fluted horizontally disposedadjusting or pinch rollers 6i (best shown in Figures 18 and 16), The rollers '61 are mounted on shafts 62 '(see Fig. 16) journalled in a bearing block t3 which is ad'justably connected to a post 65 by a braek et '64. Extended ears 66 on the bracket are retained together by any suitable means such as a bolt and wing nut 61 so that the bracket may-belo'osened-to permit of vertical and angular adjustment of the rollers "6|. As shown in'Figures 2, Hand 8, the rollers 6| extend laterally and slightly forwardly at an angle so that the fluted faces of the rollers 'frictionally engage the upper and lower surfaces of the travelling web of cloth and exert a slight lateral pull thereon so that the marginal edge "of the cloth is guided and the width thereof is controlled preparatory to formation of the latter in o a tube.

It will be understood that the width of the marginal edge of the cloth may be varied by adjusting the rollers 6| relative to the vertical axis of the supporting post '65 to vary the amount of pun which the rollers exert o the cloth. The post "6:5 is sleeved within an enlarged cylindrical collar 68 the lower end of which overlaps or spans thegap or slot 41 between the side frame members '3 and 48 and the end of the post 65 extends through the slot 41 and is clamped therein by a nut or the like 69 (Figures 7 and 16) which, upon loosening, permits of the post 65 and rollers 61 being moved longitudinally of the frame for further adjustment purposes.

'Asthe continuously moving web of cloth passes under and over the angle bar 5! the left hand marginal edge portion is passed over an elongated fluted-cylindrical cloth supporting roller 10 jour nalled on a rod 1| suitably connected by bolts or the like T2 in as'lot 14 in a horizontal plate 13 supported on the upper end of a post [5. A nut or thelike 16 serves to clamp the plate 13 to the post, and the flatter extends through asecond slot T! in the plate so that, by loosening the nut T6, the plate maybe longitudinally adjusted relative to the post. An enlarged cylindrical collar 18, "having the post 75 projecting therethrough, overlaps the slot 41 so that "the "post extends throughthe'slot and 'is clamped th'erein'by-a-nut (D on the lower endof the=post (-Figure'l'l) which,

upon' lobsening, permits ot-the post and plate 6 13 being moved longitudinally ofthe frame for adjustment. The post 15 is spaced of the adjusting rollersupportlng post it The web of cloth is thence directed downwardly a second cylindrical cloth supporting roller '80 which is circumferentlally fluted, as at 81; and is formed with a tapered outer end 8 2. Roller 89 is journalled on '"one 'end of a rod 83 the other end of which is attached to the forward end of the plate 13 by a bolt "or the like 84. The rod "83 is bent downwardly and laterally, as are; "(see Figures 7 and 17'), so that the roller '88 slopes at a slight angle below the horizontal and slightly at an angle toward the roller 10. Thus; the roller '80 is spaced 'below and offset from the roller '18 and the relative positions of the two rollers "HI and are such that the web of cloth passes over the top of the roller 10 and thence down- Wardly over and under the downwardly "slanting roller 80, after which the cloth passes ove'r under a laterallyextending horizontal 'tubeforming rod '86. By reference to Figure 7, itwill be seen that the plate '13 and supporting rollers 10 and '80 are above the plane of the adjusting rollers 6 I.

The tube forming rod 86 (Figures 7, 8 and'l '8) is carried by the outer end of a forwardly 'eiztending horizontal bracket 81 'c'onnected'by a bolt or the like 88 to theupper'end of'a post "89. The inner end of the "rod 8t is also bent slightly forwardly, as at92 (see Figures zandfl'ii). Sleeved on the post '89 is an enlarge cylindrical collar 98 which overlaps and supports the post 99 the slot 41, and the lower end of the'pos't is clamped in the slot by anut 'or'the like "9| (Figure 7). The post 8.9 is :spaced forwardly omtlie cloth roller 'supportingypost 15 'and'm'ay be adjusted relative thereto by loosening thenut "91. As thejtube "forming rod .186 extends laterally of and below the 'clothisup'por'ting rollers '10 an'd'8ll', the continuouslymoving web of cloth is directed rearwardly over and thence forwardly "under "or around the forming rod '86 so that'the left hand marginal edge or selvage of the cloth web is caused to be arranged above andin overlapping "elationship with the right hand marginal edge thereof, as best illustrated in Figure "8, preparatory to being stitched 'or otherwise connected to form the web into a tube, as hereinafter, described. V

The right handmargina'l edge of the cloth web passes over'a flathorizontal :hem guidingIplateQS suitably mounted on the base plate :94'-0"f ta conventional sewinglma'chin'e .98, it'hevbase' plate '93 of which is suitably support'ed on a flatbed plate 96 on thelmain machine frame. Thehemguiding plate is formed with fan upwardlyand mwardly bent'sid'epor'tion 91. 'As the plate 95 arranged beneath and spaced from the forming rod 86 and associated cloth supporting rods'lll and 80, it will be seen that the right hand marginal edge of the cloth engages'with the inner face .of the bent side portion '91 and is caused to be aligned withth'e overlapping left hand savage thereof in position to their being stitched or otherwise connected together. 'Ihe sewing 'machine 93 is so mounted on the main machine frame that it 'extendstran'sverselythereof "or at substantially right angles to the direction of travel of the web of-cloth. As the'usualipresser foot 98 and reciprocating needle '99, only por tion's of-which are 'shown in l 'igures 'l and 8, are arranged below the supporting ro1lers -1980 -and adjacent the bent-end 92 of the'formin'grod L86, it follows that the eve lapped marginalrnf the cloth strip are caused to pass connected by gears, longitudinal driven shaft 35, it will be understood under the presser foot 08 and to be stitched together by the threaded needle 90 to form the cloth into a tube. It will be understood that, while a means for stitching the marginal edges of the strip together has been shown and described, the same may be otherwise connected together by pasting, cementing or the like. In the present machine, the main shaft I of the sewing machine is provided with a pulley IOI on one end thereof which is drivingly connected by a belt or the like I02 with a pulley I03 on a stub shaft I04 of a gear box I05 (Figures 1A, 3 and 6) arranged on the base of the frame. As the shaft I04 is drivingly not shown, with the main that, during operation of the machine, the sewing machine will also be actuated in timed relation therewith.

After the cloth web has been formed and stitched or otherwise formed into a tube, it is necessary to pull the same away from the forming and sewing mechanism so that the tube may pass through the remaining portion of the machine. This operation is effected by a pair of horizontally disposed fluted or knurled pull rollers I00 (best shown in Figure carried by shafts I01 journalled in bearings I08 on a vertical bracket I09 on the top of the main frame. The

rollers I05 are geared together by gears I I0, and

the shaft I01 of the lower roller projects through its bearing and carries a pulley III. A belt or the like II2 rides on the pulley III and over idler pulleys H3 and H4, journalled in a vertical bracket H5 (Figure 1A) mounted on the and a. third idler pulley IIB, journalled in the base portion of the main frame, and thence over a pulley II1 adjacent the outer end of the main longitudinal driven shaft 35. Thus, the lower roller I06 is rotated in a clockwise direction, viewing Figure 8, which rotates the upper roller I08 in an opposing or counter-clockwise direction which causes the roughened surfaces thereof to frictionally engage the upper and lower surfaces of the cloth tube and to pull the same forwardly through the machine. During this movement of the cloth tube, a vertically disposed flat guide plate IIG (Figures 7 and 8) carried on a rod H9 depending from the sewing machine 03, engages the formed and twisted tube forwardly of the stitching mechanism and prevents the same from becoming entangled therein. In order to facilitate the initial entry of the cloth tube between the rollers I06, the bearing I08 for the upper pulling roll shaft I01 is mounted on its supporting bracket I09 for limited vertical movement. A'lever I (Figures 3 and 15) fulcrumed adjacent its lower end on a pin I2I arranged in the bracket I00 and the lower end of the lever bent upwardly as at 250, and has a fork 254 which engages a pin 252 on the upper bearing block I08. The lever I20 is connected intermediate its ends, as at I22, by a spring I23 to the upper end of the bracket. By moving the outer end I24 of the lever downwardly against the tension of spring I23, it will be noted that the upper roller I06 will be moved away from the lower roller.

Due to the fact that the travelling web of cloth is folded over the angularly disposed bar 5|, so that the overlapped marginal edges are stitched together on the bias, a twist is imparted to the tube which it is desirable to remove before being wound into a tube for future use, as presently described. To supplement the operation of the pull rollers I00 to assure of the tube being uni formly removed and pulled from the sewing mechanism, additional means in the form of a horizontally disposed dorfing drum I25 is provided. The dorfing drum embodies a series of fiat bars or strips I26 secured at their ends to discs I21 and extending therearound in spaced apart relation to form a hollow skeleton form. The drum I25 is mounted for rotational movement on a shaft I20 extending therethrough and journalled in brackets I20 attached to the forward end of the main machine frame at the upper end thereof, so that the drum extends transversely of the main frame in the path of travel of the cloth tube. As the various devices for feeding, folding, forming and sewing are arranged at one side of the machine, the twisted tube of cloth is caused to engage with and pass over the dorfing drum adjacent one end thereof. The dorfing drum is preferably constructed of wood or similar material because of its lightness and the fact that during the frictional engagement of the cloth therewith it will not be subjected to as much wear, as would be the case if the drum was formed of metal. A pulley I30 mounted on one end of the drurn shaft I28 is drivingly connected by a belt or the like I3I with a pulley I32 mounted on the end of the main longitudinal driven shaft so that the drum is rotated in a clockwise direction, viewing Figure 1A. After the cloth tube is engaged by the pull rollers I06 the same passes over one end of the dorfing drum whereby the spaced bars I25 thereof successively engage the cloth and impart a waving or undulating movement thereto which assures of the cloth being shaken or otherwise moved away from the sewing mechanism and the end of the angle bar 5|. As shown in Figures 1A and 3, the movement of the cloth caused by the dorfing drum may be accentuated by increasing the height of the drum bars I26 by suitably mounting relatively short strips I33 on top of the bars I23 at one end thereof.

After passing over the rotating dorfing drum I25, the cloth tube drops downwardly of the main frame. In order to remove the previously described twist from the tube, the latter is then drawn upwardly over a horizontal bar I34 supported in the upper ends of a pair of spaced upwardly and outwardly extending bracket arms I35 which are bolted or otherwise attached at their lower ends, as at I30, to the top of the main frame. The tube of cloth is drawn up further over an idle spool mounted in a suitable frame, neither of which is shown, suspended from the ceiling of a, room. The tube, after passing over the spool, is drawn or pulled downwardly by mechanism mounted upon a vertically disposed rotating turntable I31 whereby the twist is removed therefrom and the cloth tube is rewcund upon a reel for future use.

The turntable I31, best illustrated in Figures 2A and 9 to 14, consists of a substantially rectangular frame or base I38 mounted on a pair of I beam members I39. A cross member I40 has the depending shaft I4I of a relatively flat, circular, turntable carriage plate I4I journalled therein so that the plate I4I may be rotated, as hereinafter described, relative to its base I30. The plate MI is additionally supported by a series of approximately four spaced brackets I42 mounted, as at I43, on the top of the base I38 and each of which is provided with a pair of spaced idler-rollers I44 which respectively engage the top and bottom faces of an act as a bearing surface for the plate III.

Extending transversely of the turntable carriage plate I4I are a pair of horizontally disposed, parallel, rewinding rollers I45 which are rotatably mounted by stub shafts I46 in the lower ends of a pair of vertical standards I41, bolted or otherwise secured, as at I48, to the turntable plate I4I. A pair of gears I49, on one end of the rollers I45, are in mesh with each other and one of the gears I49 is in mesh with a gear I50 mounted on the end of a horizontal shaft II journalled in brackets I 52 on the underside of the circular plate I4I a slot I53 being provided in the plate through which the gear I50 extends. The shaft I5I is rotated by means of a bevel gear I54 thereon which meshes with a bevel gear I 55 on the upper end of a vertical stub shaft I56 journalled in a gear box I51 supported by a cross piece I58 mounted on the base members I39. Mounted on the lower end of shaft I56 is a gear I59 (Figure 13) which meshes with and is driven by a worm I60 on the outer end of a longitudinal drive shaft IGI of a Reeves variable speed control unit I62, of conventional construction and suitably mounted in the turntable frame I38. The other shaft I63 of the unit I 62 is provided with a. pulley I64 which is drivingly connected by a belt or the like I65 with a pulley I66 on the shaft I68 of an electric motor I61 suitably mounted on the turntable base I38. As shown in Figure 14, the annulus of the turntable plate MI is grooved, as at I69, to accommodate a drive belt or the like I which is driven by a pulley In on a vertical shaft I12 journalled in a bearing I13 (Figure 1A) on the turntable base I38. A second pulley I14 on the upper end of the shaft I12 is drivingly connected by a belt or the like I with a pulley I16 on a shaft I11 journalled in a bracket I18 suitably connected on the base I38. bracket shaft I11 is drivingly connected by a belt or the like I80 with a second pulley I8I on the end of motor shaft I68. By virtue of the drive Just described, it will be understood that the ciroular turntable carriage plate MI is rotated in counter-clockwise direction, viewing Figures 2A and 13, and the rewinding rollers I 45, upon which a winding reel or core. I82 is freely supported, are rotated in opposing directions, that is, counterclockwise and clockwise, for a purpose to be presently described.

The stub shafts I84 of one of a pair of horizontally disposed, slightly spaced, parallel rollers I83 and I 83 are journalled in suitable openings in the upper ends of vertical standards I41. The stub shafts I84 of the'other roller I83 are journalled in downwardly depending arms 206 fixedly secured to a horizontally disposed shaft 201 journalled in suitable openings in the upper ends of the vertical standards I41. Two spaced substantially U-shaped guide members 208 are sleeved on the shaft 201 and the spaced lower ends 209 thereof ride on the top faces of the rollers I83 and I83. One of the shafts I84 projects through the standard I41 and carries a sprocket I 86 which is drivingly connected by a chain or the like I81 with a sprocket I 88 on one of the rewinding roller stub shafts I46. Thus, the roller I83 is rotated in a clockwise direction (Figure 12) so that the other roller I 83' in frictionally engaging the cloth tube is rotated in an Opposing or counter-clockwise direction and the tube is pulled or drawn downwardly therebetween, in an obvious manner, to deliver the same to the winding reel or core.

flat, circular, turntable carriage During its downward travel, the cloth will pass A second pulley I19 on between and be guided by the guide members 208 on the shaft 201. The roller I 83' may be adjusted relative to its companion roller I83 to facilitate the initial entry of the cloth tube therebetween by means of depending levers 2I0 (best shown in Figure 11) on the arms 206 carried by the shaft 201 which are pivotally connected to the ends of rods 2 II in turn pivotally connected off center, as

- at 2I2, to collars 2I3 journalled on studs 2I4 in the sides of the vertical standards I41. Handles 2I5, mounted on the collars 2I3 and extending upwardly and outwardly therefrom, may be manually moved upwardly or downwardly to control the position of the roller I83 with respect to the roller I 83, in an obvious manner.

The winding reel I82 rests upon and is freely supported by the pair of horizontal bottom re-. winding rollers I45, and the extended ends of the reel shafts I89 are journalled in slots I90 in bearings I90 mounted on blocks I9I suitably connected to the lower ends of a pair of vertical rack bars I 92. The blocks I 9| are slidably arranged in longitudinal slots I93 in the vertical turntable standards I 41, and the upper ends of the rack pair of feed rollers I 83 and bars I 92 are held in position relative to the standards I 41 by means of brackets I94 connected, as at I95, to the standards. A horizontal cross shaft I96 is journalled in the brackets I94, below the I83, and gears I91 on the ends of the shaft I96 engage with the teeth I98 of the rack bars I92.

Also mounted on the other end of the cross shaft I96 is a brake drum 200 having a brake band 20I thereon. One end of the band 20I is connected by. a coil spring 202 to a pin 203 mounted in and at one side of one of the vertical standards I 41 and the other end thereof is connected to the other side of the same standard by means of a bracket 204. This last mentioned end of the band 20I passes freely over or through the bracket 204 and is pivotally connected to a handle or lever 205, so that the operator can, by actuation of the handle in a clockwise direction, viewing Figures 11 and 12, draw the brake band 20I tightly against and slow down the rotation of the brake drum 200. as the cloth tube is being wound on the reel I82, any means, not shown, being employed to lock the handle after any desired adjustmentof the band. During the vertical movement of the rack bars I92 the same engage the gears I91 on the shaft I96 and the latter rotate against the braking action of the brake band and drum, which holds the lower end of the rack bars against the windin reel shafts so that the winding reel is retained in engagement with the bottom rewinding rollers I45. This causes the tube of cloth to be pressed a ainst and to be wound tightly around the reel I82.

During the winding of the cloth tube on the winding reel I82the latter will ride upwardly in the turntable standards until the desired amount of cloth has been wound thereeround. At such time, if the cloth supply has not been exhausted, the cloth tube is suitably severed at a. point below the rollers I 83 and I 83' so that the reel I82 may be removed from the turntable. To facilitate the removal of the winding reel shafts, shaft I89 from the slots I in the rack bearing I90, the shaft I96 may be further rotated by a, hand wheel I99 mounted thereon, so that the racks I92 are elevated and the bearing slots I90 are moved out of engagement with the reel stub shafts I89. This permits of the cloth reel being lifted out of the turntable, in an obvious manner.

Although the turntable mechanism has been
